Performance Procedures

LED Excitation This procedure uses normal system components to test circuit operation. A SpO2, adult Test finger, reusable sensor is used to examine LED intensity control. The red LED is used to

verify intensity modulation caused by the LED intensity control circuit.

Step

Action

1

Connect an SpO2 sensor to the monitor.

2

Press the On/Standby button to turn the monitor On.

 

 

3

After the monitor completes its normal power-up sequence, verify that the sensor

 

LED is brightly lit.

 

 

4

Slowly move the sensor LED in proximity to the photo detector element of the

 

sensor. Verify, as the LED approaches the optical sensor, that the LED intensity

 

decreases.

 

 

5

Open the sensor and take note that the LED intensity increases.

 

 

6

Repeat Step 5 and the intensity again decreases. This variation is an indication

 

that the micro-processor is in proper control of LED intensity.

 

 

7

Turn the monitor Off.
